Re: Outdrive oil leaking into bilge
Alrighty so it seems I'm looking at an upper and lower seal kit
i think your just looking at the ft. seal of the drive. the one in bd's link. #21.
for sure R&R the bellows.
for sure R&R the gimble brg. if it got wet. it'll rust in the end and fail. feels good now or not.
i had about the same job as your doing when i got my boat. here's my list of things i replaced
bellows
shift cable and shift cable bellows
shift shaft
shift lever
shift shaft seal (new style)
water hose
gimble brg
ujoints
ft seal of the upper
yoke
brg. assy.
for tools, just read the s/m. it'll list any tools necessary. if your lucky and only have to do the ft. seal. ya may get away with only the spanner wrench. if you replace anything other than the ft. seal. ie, gears, brgs. you'll need to reshim.
this is why ya do the yoke (item #11).
note the rust right at where the seal rides at. this rust is what destroys the seal and causes the lub to leak out. the rust was caused by the water intrusion into the bellows area.
this is the assy. your going after. the seal (on the right) is the second to last thing to remove from the stack. nut on left was first item to remove.
i ended up getting a new torque wrench for the project. i wanted to be in the middle of the torque wrench capabilities to set to spec.
also, if ya don't have the small spacer in the brg. pack. you will use rolling torque to tighten down the nut.
if your gonna tear into this. ya gotta have a service manual if you hope to succeed with the repair.
do a pressure/vac test when done to be sure yer sealed up.
edit. get a ujoint press too for the ujoints. + there's a special mercruiser adaptor to use for the ujoints. these two tools make short work of the ujoints.
